I was recently provided with a 2004 F250 Superduty for work (used). It has a keypad to unlock the door however I was not provided with the code and it is not written in the user manual. I do not know how to get in contact with the previous owner. Is there somewhere in the truck that this code is located or is there a better way of getting it? We thought it would be located under the steering column but we couldn't find it there.
